Description of the Invention: [Technical Field] The present invention relates to a liquid crystal display, and more particularly to a frame set of a liquid crystal display. [Prior Art] With the advancement of technology and the rapid development of the media, users have higher and higher requirements for the sound and light effects of peripheral devices. In the past, the commonly used cathode ray tube (CRT) display, due to its large size, has become less and less demanding in today's era of light and thin. Therefore, in recent years, many flat panel display technologies have been developed, such as liquid crystal displays (LCDs), which have gradually become the mainstream of displays. Due to the rapid development and maturity of the technology, liquid crystal displays are much smaller in space and weight than the same size video tube displays. It is precisely because of these trend-setting advantages that LCD displays are widely used in various electronic products. In the related applications of various liquid crystal displays, the growth of LCD TVs is even more amazing. At present, the size of LCD TVs has even surpassed the plasma TVs which are traditionally considered to be large sizes. This type of liquid crystal display has a special feature. · The drive circuit board is mostly fixed to the side of the plastic frame. In order to achieve this goal, in addition to the need to set the wall on the plastic frame, the assembler often needs additional locking screws to secure the drive circuit board and provide the required grounding function. However, although the screw locking method seems to be effective, it will cause problems in the assembly, such as various parts, time-consuming assembly, and heavy work. Therefore, 'how to develop a simple and effective board fixing method' has become an urgent problem for related industries. SUMMARY OF THE INVENTION - Therefore, a technical aspect of the present invention relates to a liquid crystal display, wherein k is used to fix a printed circuit board to a plastic frame by using a positioning post. * Q One embodiment of the liquid crystal display of the present invention comprises a plastic frame and a printed circuit Plate, positioning post, slot, first restraint and liquid crystal panel. The printed circuit board has at least one fixing hole therethrough. The positioning post is formed on the plastic frame. The slot is formed in the positioning post and disposed along the long axis of the positioning post. The first restraining member is disposed on a side wall of the positioning post such that the printed circuit board is restrained between the first restraining member and the bezel. The liquid crystal panel is located in the plastic frame and electrically connected to the printed circuit board. Another aspect of the present invention relates to a frame set that can be used in conjunction with Q. The liquid crystal display of the present invention includes an adhesive frame, a printed circuit board, a positioning post, a slot, and a first restraint member. The printed circuit board has at least one fixed aperture therethrough. The positioning post is formed on the knee frame. The slot is formed in the positioning post and disposed along the long axis of the positioning post. The first restraining member is disposed on the side wall of the positioning post such that the printed circuit board is restrained between the first restraining member and the bezel. [Embodiment] Fig. 1 is a perspective view showing a perspective of an embodiment of a liquid crystal display of the present invention 200949359. As shown, the liquid crystal display 100 can include a bezel 110, a printed circuit board 120, a liquid crystal panel 200, and a front bezel 300. The liquid crystal panel 200 is located in the plastic frame 110 and electrically connected to the printed circuit board 120. The printed circuit board 120 is fixed to the side of the plastic frame 110. The front bezel 300 covers the plastic frame 110, the printed circuit board 120, and the liquid crystal panel 200 such that the above-described respective components are formed into the liquid crystal display 100. Fig. 2 is an enlarged view showing a portion of the liquid crystal display device 100 of Fig. 1 after being assembled on the printed circuit board 120. Fig. 3 is a cross-sectional view taken along line 3 of Fig. 2. As shown, in order to fix the printed circuit board 120 to the side of the plastic frame 110, the liquid crystal display 100 of the present embodiment includes a positioning post 130, a slot 140, and a first restraint member 150. The positioning post 130 is formed on the plastic frame 110. The slot 140 is formed in the positioning post 130 and disposed along the long axis of the positioning post 130. The first restraint member 150 is disposed on the side wall of the positioning weir 130. The printed circuit board 120 can have at least one fixing hole 122 extending therein. In use, the user can first align the fixing hole 122 with the positioning post 130. Next, the user can press the printed circuit board 120 to squeeze the first restraint member 150 on the side wall of the positioning post 130. At this time, due to the existence of the slot 140, the positioning post 130 is compressed and deformed into the slot 140, and the first restraint member 150 is passed through the fixing hole 122. Once the first restraint member 150 passes through the fixing hole 122, the positioning post 130 will rebound immediately, so that the first restraint member 150 abuts against the side of the printed circuit board 120 facing the plastic frame 110. As a result, since the positioning post 130 has been inserted into the fixing hole 122 of the printed circuit board 120 at this time, the movement of the printed circuit board 120 in the direction X and the square 200949359 to Y will be restricted by the positioning post 130. On the other hand, since the first restraining member 150 abuts against the side of the printed circuit board 120 facing the plastic frame 110, the movement of the printed circuit board 120 in the direction 亦 will also be restrained (that is, the printed circuit board 120 will be restrained on Between the first restraint member 150 and the plastic frame 110). In summary, the combination of the positioning post 130 and the first restraint member 150 will be sufficient to fix the position of the printed circuit board 120 on the plastic frame 110, thereby completely replacing the conventional screw positioning function. In addition, the structures of Figures 1 and 2 can also be considered as a frame assembly 105 comprising a plastic frame 110, a printed circuit board 120, a positioning post 130, a slot 140 and a first restraint member 150. The printed circuit board 120 has at least one fixing hole 122 extending therethrough. The positioning post 130 is formed on the plastic frame 110. The slot holes 140 are formed in the positioning post 130 and are disposed along the long axis of the positioning post 130. The first restraint member 150 is disposed on the side wall of the positioning post 130 such that the printed circuit board 120 is restrained between the first restraint member 150 and the bezel 110. In order to install the printed circuit board 120 more easily, the material of the positioning post 130 can be a flexible material, allowing the user to obtain a larger amount of deformation with a smaller pressing force. Specifically, the material of the positioning post 130 of this embodiment may be polycarbonate (PC). The above-mentioned materials are merely illustrative and are not intended to limit the invention, and those skilled in the art to which the invention pertains can select an embodiment of the invention. Referring to FIG. 3, the present embodiment also adopts the following two structures to improve the deflection of the positioning post 130, one of which is a hollow shell as the structure of the positioning post 130 described above, and the other is to extend the slot 140 to a portion thereof. The plastic frame 110 (as indicated by the arrow P in Fig. 4). The above two structures may exist independently of 200949359, and those skilled in the art to which the present invention pertains may adopt appropriate structures according to specific needs. Referring to Figures 1 and 4, the liquid crystal display 100 of the present embodiment includes at least one second restraint member 160 positioned on the plastic frame 110 and against the printed circuit board 120. In particular, the second restraint member 160 is designed to interfere slightly with the printed circuit board 120 to prevent the printed circuit board 120 from swaying or vibrating in the direction Z. The micro-interference described above means that the vertical distance between the second restraint member 160 and the first restraint member 150 is slightly smaller than the thickness of the printed circuit board 120, so that after the printed circuit board 120 is mounted, the second restraint member 160 is slightly Deformed under pressure. For example, if the thickness of the printed circuit board 120 is 0.8 mm, the vertical distance between the second restraint member 160 and the first restraint member 150 can be designed to be 0.6 mm. The positioning post 130 can also slightly interfere with the fixing hole 122 of the printed circuit board 120 to prevent the printed circuit board 120 from shaking or vibrating in the direction X or the direction Y. Similarly, the slight over interference means that the size (eg, diameter) of the positioning post 130 is slightly larger than the size (eg, diameter) of the fixing hole 122 of the printed circuit board 120, so that after the printed circuit board 120 is mounted, the positioning post 130 is slightly compressed. Deformation. When disassembling, the user only needs to apply force to compress and deform the positioning post 130 into the slot 140, so that the first restraint member 150 is retracted into the fixing hole 122 of the printed circuit board 120. At this time, since the second restraint 160 which is originally deformed by pressure is automatically rebounded, the printed circuit board 120 is naturally pushed out of the positioning post 130 without the user having to perform other operations. It can be seen from the above that the present embodiment can not only use the positioning post 130, the first restraint 9 200949359 bundle 150 and the second restraint member i6 取代 to replace the function of the conventional screw positioning, and the loading and unloading of the printed circuit board 120 does not require an additional hand. Tools and complicated operations can effectively solve the problems caused by traditional screw locking. The plastic frame 110, the positioning post 13A, the first restraining member 15A and the second restraining member 160 of the embodiment can be integrally formed. More specifically, the above-mentioned plastic frame ‘U〇, positioning post 13〇, first restraint member 150 and second restraint member 16〇 may be made of polycarbonate for injection molding. The above materials and manufacturing methods are merely illustrative and are not intended to limit the present invention. Those skilled in the art to which the present invention pertains can select suitable materials and manufacturing methods according to specific needs. In the second embodiment, the liquid crystal display 100 has at least one grounding screw 170 that is attached to the grounding position of the printed circuit board 12A to provide a desired ground potential. The grounding screw 17 is not required, and those skilled in the art to which the invention pertains may also provide the desired ground potential in other suitable manners. For example, the user can also directly use the metal back plate of the inside of the plastic frame to provide the ground potential without additional locking of the grounding screw. The following embodiments will specifically disclose how to implement the above technical content. Fig. 5 is a cross-sectional view showing another embodiment of the present invention, the cross-sectional direction of which is the same as that of Fig. 3. Fig. 6 is a perspective view showing the printed circuit board 120 of Fig. 5 removed. As shown by the circle, the embodiment includes a hole 12 which penetrates the frame 110 and exposes the metal back plate ι8〇 located inside the frame 110. The second restraining member 160 is disposed on the metal back plate 18 , and passes through the hole to abut the grounding position of the printed circuit board 120 to provide a required grounding power 200949359. The second restraining member 160 of the embodiment can be The metal back plate 18 is integrally formed.
